Summary
Introduction:
This article presents a study that aimed to evaluate and compare the acute effects of tobacco cigarette (TC) smoking and electronic cigarette (EC) vaping on foveal and choroidal thickness in young, healthy, dual smokers. The study is important as it examines the potential impact of EC use on eye health, a topic that has not been extensively studied.
Key Points:
* The study included 47 participants who were young, healthy, dual smokers.
* Participants underwent four trials: 5 min TC; 5 min EC; 30 min EC; and 60 min sham trial.
* Scans before and immediately after each trial were obtained using spectral domain optical coherence tomography with the enhanced depth imaging mode.
* Changes in central foveal thickness (CFT), subfoveal choroidal thickness (SFCT), and CT at four other points were measured.
* The study did not observe any statistically significant change in SFCT, CFT, and CT of the other points after any of the four trials.
* The acute changes in CFT and CT after EC vaping or TC smoking did not differ significantly compared to the sham trial.
Main Message:
The study suggests that smoking and vaping do not result in statistically significant acute alterations in foveal and choroidal thickness in young, dual smokers. This finding is important as it adds to the understanding of the potential health effects of EC use, particularly in the eye. however, further research is needed to determine the long-term effects of EC use on eye health.
